TC63i AT Command Set
10.2 AT^SICI
(num)
Number of services using this Internet connection profile.
0...9
(str)
Local IP address of the Internet connection profile (empty if no address is associated yet).
Notes
• Before opening a service profile based on a connection profile recently used, check with AT^SICI that the
previous connection was properly closed. If AT^SICI confirms that the connection profile is in
0 (Down) the connection profile may be used again.
• If AT^SICI is used simultaneously on different instances (e.g. Mux channels) only one request can be handled
at a time. On the other instance(s) "+CME ERROR: operation temporary not allowed" will be displayed.
If so, repeat the command on this instance.
• After closing the last service which uses this connection profile, parameter value is
decreased after the expiry of the inactivity timeout "inactTO" of AT^SICS only.
10.2.1 Checking Connection Profile Status
at^sici?
^SICI: 1,2,1,"10.10.0.161"
OK
Query the current status of the connection profile.
One connection profile has been created at =1, and one service is opened using
this connection profile. The Internet connection is in
=2 ("Up").
Assume the network connection is temporarily not available. (If URC presentation mode of network registration
is enabled the state is shown by the URC "+CREG: 2").
at^sici?
^SICI: 1,3,1,"10.10.0.161"
OK
Query once again the current status of the connection
profile.
Parameter has changed to state "Limited
up".
The network connection is temporarily not available but the Internet connection is still established, so the host
may decide to stop the data transfer to minimize the risk of losing data due to memory limitations.
at^sici?
^SICI: 1,2,1,"10.10.0.161"
OK
Another service has been opened with AT^SISO:
at^sici?
^SICI: 1,2,2,"10.10.0.161"
OK
After closing one service with AT^SISC:
Query once again the current status of the connection
profile.
After re-establishing the network connection, reverts to state "Up".
Query once again the current status of the connection
profile.
After opening another service, parameter
has increased.
